CROZING IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 409,235, dated August20, 1889.

Application filed August 1, 1888.

To all whom, it may concern:

Be it known that I, LEMON M. REED, of Cleveland, in the county ofOuyahoga and State of Ohio, have invented certain new and usefulImprovements in Or zing-Hachines; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it pertains to make anduse the same.

My invention relates to improvements in crozing-maehines in which thestaves during their passage through the machine are bent to correspondwith the bilge of the barrel, keg, or vessel for which they areintended, and while so bent are crozed, cut to lengths, and afterwarddischarged from the machine, the operations of the machine beingentirely automatic.

In the accompanying drawings, Figure l is a side elevation. Fig. 2 is aplan. Fig. 3 is an enlarged side elevation in section. Figs. 4 and 5 areend views enlarged and in detail.

A represents the supporting-frame, having suitable boxes, in which arejournaled, re spectively, the large shaft B, the spindles O C, andcounter-shaft D. Shaft B is provided with driving-pulley B, mountedloosely on the shaft, with pinion B integral or rigidly secured to thehub of the driving-pulley, the pinion consequently revolving loose onshaft B. This pinion engages a larger gear (Z of shaft D, and on thesame shaft is mounted pinion d, the latter engaging a larger gear Bf,the latter gear being mounted on and keyed fast to shaft B for rotatingthe latter. By such train of gearing the faster speed, such as wouldordinarily be transmitted from a lined shaft to pulley B, is reduced toa slow speed suitable for shaft B. Spindles O 0, carryingthecutter-heads, are run ata high speed, and are therefore driven direct bybelts applied to pulleys C C. On shaft B is mounted a sectional formercomposed of sections Z) and b I), such former having the generalappearance of a barrel or cask. The middle section Z) is keyed fast tothe shaft, sections 1') b bein g adjustable lengthwise of the shaftaccording as the staves are to be bent more or less to correspond withthe greater or less bilge of the barrel or keg for which such staves areerial No. 281,675. (No model.)

intended. The sections I) are keyed to the shaft, so that they rotatewith same, but can be moved longitudinally thereon by loosening screws owhich latter are mounted in the hubs of the sections and bear againstthe shaft. It will be observed that section b has a crowning face andthat sections 1) have beveled and slightly-rounded faces placed inreversed order.

By contracting the formerthat is, by moving sections Z) 1) toward eachother-the staves when pressed upon the periphery of the former are bentmore, and by expanding the former the staves are bent less.

The mechanism for bending the staves to fit the former is as follows:Presser-bars E, having curved and prefe ably circular spaces of somewhatgreater radius than the section Z), are secured to the frame-work of themachine. These presserbars are located, as shown, near the end of theformer but outside the lines thereof. The presser-bars being eccentricwith the aXis of the former, the upper end (2 of the presser-bars beingfar enough removed from the former to admit a straight stave between theformer and presser-bars. At points 6' the presser-bars approach to nearthe axis of the former as to bend the staves inward onto sections 1),thus making the staves fit the former, and consequently shaping thestaves to conform to the shape the staves will assume when placed in thekeg or barrel for which they are intended. While the staves are thusbent on the former, the cutter-heads c e do their work on the successivestaves as they pass,beveling the ends of the staves shown at f andcutting the crozings, as shown at f also, saws c 0, connected with therespective cutter-heads, cut the staves to lengths at the sameoperation. Beyond the cutter heads bars E recede from the former, sothat the staves gradually unbend and at length fall by gravity uponapron K, and are carried from under the machine on the apron. The stavesF are piled against the standards G, G, and H, the lower staves restingon the revolving former below. Sections 1) of the former are providedwith projecting members-for instance, with series of blocks I, securedto the rims of these sections by means each of a single pivotal pin orbolt i. The blocks are arranged in pairs 011 planes parallel with theaxis of the former, and the successive pairs of blocks engage thesuccessive staves of the pile, carrying such staves under barsG with theresult aforesaid.

It will be observed that the operations of the machine are entirelyautomatic and that the staves are crozed while they are bent to conformwith the bilge of the barrel or keg for which they are intended, andthat while they are so bent they are cut to lengths and afterwarddischarged in a completed condition from the machine. It will also beobserved that the cutter-heads operate directly opposite, orapproximately opposite, the presser-bars, and consequently the staves inpassing are not only crozed and beveled and out to lengths, but are alsodressed to thickness Where such crozing and bevelin g occur.

What I claim is-- 1. In a stave-crozing machine, the combination, with aformer made up of center and end sections, the latter having projectionsthereon for engaging the staves and adjustably secured on the shaft,whereby they can be moved toward and away from the central section,curved presser-bars located at one side of the vertical center of theformer, and standards for supporting a series of staves, the saidstandards being located adjacent to and in front of the upper ends ofthe presserbars, of cutter-heads for crozing and dressing the ends ofthe staves and cutting the latter into lengths, substantially as setforth.

2. The combination, with a sectional former and cutter-heads for cuttingand dressing the ends of the staves, of the presser-bars located whollyto one side of the vertical center of the former, and standards alsolocated on the same side of the vertical center of the former andadapted to support a number of staves, substantially as set forth.

In testimony whereof I sign this specification, in the presence of twowitnesses, this 8th day of June, 1888.
